The aircraft was to be powered by two General Electric F412-D5F2 turbofan engines, each producing about 13,000 pounds-force (58 kN) of thrust. It was designed to carry precision guided weapons internally.Watch the video from Found And Explained:
Although the A-12 Avenger II utilized a flying wing design, its overall shape differed from the triangular B-2 Spirit under development for the Air Force.the A-12 Avenger was never intended to scream into the fight with its teeth bared.

The aircraft suffered many problems during development, particularly with materials , and when the projected cost for each aircraft reached US$165 million, the project was canceled by then-Secretary of Defense Dick Cheney in January 1991./wikipedia
